Abstract

In some embodiments, a shrub removing apparatus may include one or more of the following features: (a) a chain segment having a chain link, (b) a barb coupled to the chain link, (c) a first circular ring coupled to the chain segment at a proximal end, and (d) a second circular ring coupled to the chain segment at a distal end.

Claims

exact text as granted — not AI-modified
1. A shrub removing apparatus comprising:
 (a) first and second ring members; and 
 (b) a plurality of chain segments of generally equal length, each of the segments comprising a plurality of links where some of the links have a barb member affixed to them where the barb members extend across the links in a direction transverse to a length dimension of the chains, said chains being attached to the first and second ring members in a parallel arrangement where the ring members are of a differing diameter whereby the first ring member may pass through a central opening of the second ring member to form a loop. 
 
     
     
       2. The shrub removing apparatus of  claim 1  wherein links of the chains are of a generally oval shape that has been twisted about a minor axis of the oval shape. 
     
     
       3. The shrub removing apparatus of  claim 2  wherein opposed ends of the chains are welded individually to the first and second ring members and the barbs are welded to the links. 
     
     
       4. A method of extracting a shrub, roots and all, from the earth in which it is growing comprising the steps of:
 (a) providing the apparatus of  claim 1 ; 
 (b) wrapping the chain segments about a stem of a shrub to be extracted; 
 (c) feeding the first ring member through the central opening of the second ring member to form a loop encompassing the stems of the shrub; and 
 (d) applying a pulling force to the first ring member sufficient to extract the shrub from the ground. 
 
     
     
       5. The method of  claim 4  wherein the pulling force is provided by a motorized vehicle to which the first ring member is attached.
